TOPIC: New Supercharger kit for the 1978-86 16v 928 coming out!

We are re-designing our supercharger kit for the 78-86 16v Porsche 928: The early 16v 928's were our very first kits, and we built them around a Powerdyne supercharger. Later kits were developed by us for the 32v 928 and the Ferrari 308, 328 and Mondial's using the Raptor V Supercharger because of its higher outputs and smaller size.. We have had great results with the Raptor, so much so that we are re-engineering our old Powerdyne kit to use the Raptor VL instead. The Raptor powers the 5.0L 928 so well, we know it will have no trouble at all with the 4.7 and 4.5L models. Here is a pic of our new Raptor kit for the 16v 928 installed.

I own an 1979 Porsche 928 engine code M28 / 03, 219 Hp. How much is that updated supercharger going to sell for and how fast can I expect it to be my door. Is it going to come with all I need to do the job or am I gone need to buy some other accessories ? Do I need to program my ECU ? Can I to get some extra power.

What type of HP increase can I expect from this Kit ? I'm ready to buy it provided that it's a reasonable price.
